Abstract: The title compound, [Cu(CHO₂)₂(C₁₄H₁₂N₂)]·H₂O, consists of solvent water molecules and one-dimensional [Cu(dmph)(HCOO)(-HCOO)_2/2]_n polymeric chains (dmph = 4,7-dimethyl-1,10-phenanthroline). The polymeric chains are generated from the [Cu(dmph)(HCOO)]⁺ units bridged by formate anions. The Cu atom is coordinated in a square-pyramidal environment. Interdigitation of the polymeric chains results in two-dimensional layers, which are stabilized by interchain - stacking interactions (mean 3.53 Å). The supramolecular assembly of the resulting layers is accomplished by interlayer C-HO hydrogen-bonding interactions.
